4 Claims. to]. 203-280) This invention relates to a thread or strandstorage device of the reel type adapted to take on a strand at one end,feed the strand in spiral form along the length of the device anddischarge the strand at the opposite end.

Among the objects of the invention is to provide a strand storage deviceof the type specified in which the strand which is stored thereon is notunder tension and does not bind the parts of the reel in any way.

Among other objects of the invention is to provide a thread or strandstorage reel which is adapted to operate with different strand materialshaving high variations of flexibility, with strand materials of variousdegrees of elasticity and with strands of relatively thick crosssectional areas.

While the strand material is being stored it may be treated with variousliquid treating agents.

The objects of the invention are attained by providing a two partcombination reel, a first part of which rotates inside of the secondpart, the first part of which is adapted to carry the strand on itsoutside surface and the second part of which is adapted to carry thestrand material on its inside surface. One reel part is made to rotatein a. circular or elliptical path which is at an angle to the circularpath of the other reel part. When the strand material rests on the firstreel part it moves in a different direction than when it rests on thesecond reel part. The said second reel part is rotatably supported fromthe outside. The two parts are rotated so that the peripheral speed ofthe outside surface of the first part is substantially equal to theperipheral speed of the inside strand contacting surface of the secondpart.

The combination reel may be used for temporarily storing a large tow orbundle of threads, flexible wires, a linear woven or knitted fabric,etc.

The reel combination may be positioned in a bath for dip treating thestrand being stored or the strand material may be sprayed with thedesired treating liquid or with drying air, for example, during storage.

Examples of treatments which may be applied to the strand are dyeing,desulfurizing, bleaching, drying, in the case of yarns and fabrics orpickling, electroplating, etc.- in the case of metal strands.

The invention together with additional objects and advantages thereofwill be better understood from the following examples of a specificembodiment thereof when read in connection with the accompanying drawingwherein:

Fig. 1 is a side view of the storage device.

Fig. 2 is an end view of the device dipping into a treating bath.

Fig. 3 is a detail view of a part of the outside reel portion.

The storage device of the invention comprises an inside reel or rollerportion and an outside reel portion 30. The strand material 50, which isillustrated, is a relatively flexible bundle of fibers, but any type ofstrand material capable of hanging in a series of loops about thecentral roller 10 may be stored although a stifier bundle or stripmaterial will not hang as loosely as the bundle 50 which is illustrated.i

The outside portion 30 is reel shaped but in some instances may have acontinuous inside surface instead of being formed of bars 31 as shown.The inside roller 10 and the reel 30 are rotated so that the peripheralspeed of the outside of roller 10 equals the speed of one of bars 31 ofthe reel 30, or in other words the parts of the two portions 10 and 30which together carry the strand material 50 travel at substantially thesame speed. How

ever, these two portions do not travel in concentric paths although theroller 10 is approximately the same length as the reel 30 and isapproximately symmetrically positioned within said reel 30. While thestrand material is moving along with the upper part of roller 10, it isalso moving axially (to the right as shown in Fig. 1) with respect toreel 30, and/or conversely when the strand material 50 is resting on thelowermost rods 31 of reel 30 and moving therewith, it is moving axially(to the right as shown) with respect to roller 10. This effect may beobtained (especially when the length of the store device is shortcompared to the diameter of the outside reel) by simply mounting theinside roller 10 and the outside portion 30 (which in this case may becontinuous and cylindrical in form) to rotate about substantiallyhorizontal axes located in different vertical planes which cross eachother.

In the device shown the roller 10 rotates about a substantiallyhorizontal axis 11-12 and each point on the reel 30 rotates about theroller 10 as if the point were mounted on a substantially horizontalaxis which is in a vertical plane at anangle to the vertical plane ofaxis 11-12 of the portion 10. However, the rods 31 are so mounted onreel member 30 and the reel itself is mounted on pulleys or rollers 32,33, 34, etc. that rods 31 oscillate axially back and forth once, withrespect to the roller 10 during each rotation. This effect is obtainableby virtue of the pivotal mounting the rods 31 on the rings 35, 35, bylinks 36 which are pivotally attached to the rods as shown in Fig. 3. Inthis way the rollers 32, 33, 34, etc. which in eifect guide the axialmovement of the rods 31 during rotation may be adjusted to givediiferent degrees of axial movement with each rotation.

As shown in Fig. 2, guide pulleys or rollers 33 and 34 may be positionedinside a bath or container 40 capable of holding treating liquid 45 forthe material 50. Rollers 34, for example, may be mounted in bath 40 bymeans of brackets 41, 42. The member 30 may be rotated by driving one ormore of the rollers 32, 33, 34, etc. The inside roller 10 is driven fromthe axle 11 or 12. As stated above the two members are driven at such aspeed that the outside peripheral speed of roller 10 equals the speed ofthe inside surface of one of rods 31. If it is not convenient to driveone of rollers 32, 33, 34, the reel member 30 may be driven by anendless belt passing partially around the same.

As shown in Fig. 1, the bundle of fibers 50 is fed onto the top portionof roller It) and allowed to pass downwardly until it contacts a bar 31.The bar 31 carries the bundle around and to the right (as shown inFig. 1) and when the bundle next passes to the surface of roller 10 itis axially spaced from the region where the bundle first contacts saidroller 10, and so on with each loop of the bundle 50. The bundle may bethreaded onto the device by attaching an end thereof to a continuous,more or less flexible, ring of approximately the diameter and size ofone spiral turn of the bundle within the store device.
